CHARLES ROIBSON, OF PHILADELPHIA, PENNSYLVANIA.

BAKER S-OVEN LAMP.

Application filed September 7, 1905.

To all whom it may concern:

Be it known that I, Ci-IARLns RoBsoN, a citizen of the United States,residing at the city of Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented a new and useful Bakers Oven Lamp,of which the following is a specification.

Objects of the present invention are to provide a simple, reliable andcomparatively inexpensive lamp for lighting bakers ovens; to so arrangeand construct the parts of the device that the same can be readilyarranged in position for use and are accessible for repairs from theoutside of the oven; and to facilitate lighting the device and actuatingthe hood which is used for covering it when not in operation.

To these and other ends hereinafter set forth the invention, stated ingeneral terms, comprises the improvements to be presently described andfinally claimed.

The nature, characteristic features and scope of my invention will bemore fully understood from the following description taken in connectionwith the accompanying drawings forming part hereof and in which Figure1, is a perspective view with parts broken away and illustrating a lampembodying features of the invention. Fig. 2, is a face viewof the lamp.Fig. 3, is a top or plan view illustrating details of construction. Fig.4, is a plan view, partly in section, taken below the revoluble part ofthe device, and Fig. 5, is a sectional plan view, drawn to an enlargedscale, of the gas cock.

In the drawings 1, is a housing having a curved end 2, provided with anopening 3, and having a sloping top 4, and an open end 5. This housingcontains all the parts of the lamp, as will be described, and it ismounted in the wall of the oven in such a way that the opening 3, isexposed at the interior of the oven, and the opening 5, is

accessible from the exterior of the oven.

\Vithin the housing 1, is arranged a cylindrical casing 6, constitutinga lantern and having one-half of its cylindrical surface opaque and theother half fitted with a transparent window as of mica 7. The top andbottom of the cylindrical lantern are slotted as at 8, Fig. 3, and thebottom of the lantern is provided with a pivot mounted in the bracket 9,while the top of the lantern is provided with a pivot 10, mounted in aSpecification of Letters Patent.

bearing 11, by means of a pin 12. The bracket 9, and bearing 11, aresecured to the top and bottom of the housing 1, and the lantern isrotatable about its vertical axis. By withdrawing the pin 12, thelantern may be readily applied to and removed from the housing 1.

13, is a handle pivoted to a stud 14, depending from the base of thelantern and it affords means for turning the lantern a part of arevolution sufficient to bring the transparent window 7, into and out ofalinement with the opening 3.

15, is a burner connected with the up turned end of a gas pipe 16, whichis secured to the floor of the housing 1, for example, by means of thekeeper 17. The upturned end of the gas pipe as well as the rods 18,which carry the reflector 19, are accommodated by the opening 8, in thebase of the lantern.

20, is the gas regulating valve and the shank of its plug is providedwith an opening through which freely works the rod 21. The rod 21, ispivoted to the lug 14, so that when the lantern is turned to bring itswindow opposite the opening 3, the gas is turned on so as to produce abright light and when the lantern is turned in the opposite directionthe gas is turned down to a pilot flame. The pilot flame is produced bymeans of a bypass groove 22, the effective size of which can beregulated by means of the point of a set screw 23.

If desired the part of the bracket 9, to which the rods 18, areconnected may be fitted with an appropriate socket for an electric lamp.

It will be obvious to those skilled in the art to which my inventionappertains that modifications may be made in detail without departingfrom the spirit thereof, hence the invention is not limited further thanthe prior state of the art may require, but

Having thus described the nature and objects of my invention, what Iclaim as new and desire to secure by Letters Patent is:

A bakers oven lamp comprising the combination of a housing openat oneend and having its other end cylindrical and provided with an opening, acylindrical casing pivotally arranged in the housing and provided with atransparent and an opaque wall, a handle connected with the casing forturning it, an immovable burner having fixed gas connections including arotary plug valve provided in its shank with a In testimony whereof Ihave hereunto through opening, and a rod pivoted to the signed my name.casin and slidable throu h the opening 1 T Whergby When the casing is?turned the rod CHARLEb ROBSO1\' 5 slides through the opening in theshank of In the presence oi' the valve plug and turns the latter,substan- O'ms EGAN, tially as described.
